Low diversity in protein sizes
Which centrality measure identifies proteins that act as key connectors between different parts of the network?
Betweenness centrality
How do degree centrality measures define the importance of a protein in a network?
Based on the number of connections the protein has
If a protein has a high betweenness centrality, what can be inferred about its role in a protein interaction network?
It is crucial for connecting different parts of the network

What is the primary function of network motifs in the context of biological networks?
To predict the function of genes or proteins
How do network motifs and communities differ in their representation of biological entities?
Network motifs represent patterns of connections, while communities represent groups of organisms
Which of the following statements best describes the relationship between network motifs and communities in biological networks?
Network motifs can exist within communities, but they are not equivalent to communities
